The ministry said many organisations and persons took advantage of information technology and the internet to organise online gambling rings through betting or card games. Rikvip began operations on April 18, 2015 on the websites rikvip.com and rikvip.vn, featuring 42 games simulating different forms of gambling. They also used the National Payment Corporation of Vietnam (NAPAS) services to help gamblers send money to game accounts from bank accounts while issuing Vcard and GoCoin game cards with the same purpose. The gambling organisers set up a system of gambling agencies nationwide, including 25 tierl-1 agencies and 5,852 tier-2 agencies. Leaders of the ministry assigned the investigation to the Investigation Security Agency under the Department of Public Security of Phu Tho province.
